COMBINED HAY SWEEP AND TEDDER- SPECIFICATION forming part of LettersPatent No. 333,917, dated January 5,1886.

Application filed July 2, 1885. Serial No. 170,457. (No model.)

To all whom, it may concern.-

Be it known that I, THOMAS S. BROWN, of the city of Poughkeepsie andState of New York, have invented a new and useful Improvement inCombined Hay Sweepers and Tedders, of which the following is aspecification.

The object of my invention is to provide a machine by which hay or strawmay be raked or gathered into a windrow or into a pile at the center ofthe area swept by the machine, or by which formed windrows may be turnedover; and, generally stated, it consists of a main frame mounted uponand supported by two wheels and provided at its under side with acircular tooth-frame carrying sweeping-teeth and adapted, by suitablemechanism, to be revolved as the machine is moved forward, as ishereinafter more particularly described.

In the drawings, Figure l is a rear view in perspective of my invention.Fig. 2 is a top plan view of part of the main frame and of thetooth-frame, and of devices by which the teeth are caused to press uponor be lifted from the ground. Fig. 3 is a top plan view of part of theplatform, thills, and devices by which the platform and thills areconnected together. Fig. 4 is a side elevation of the parts shown inFig. 3. Fig. 5 is a rear elevation of parts of the divided axle and ofthe universal joint by which said parts are connected, and of thedevices which support the tooth carrying frame, and of the mechanism bywhich said frame is caused to revolve. Fig. 6 is a view in perspectiveshowing the switch by which the teeth of the machine are caused to bebrought into or out of contact with the ground.

A is a rectangular main frame having a forward projection, B, whichconstitutes the platform of the machine, and upon which the drivers seatB is mounted. This main frame is supported by the divided axle F F, uponwhich the supporting-wheels G are loosely mounted. The divided axle F Fis at its center coupled or connected by a universal joint, H, and hasits bearings in blocks E, E, E, and E, which are respectively housed inframes D D D D, rigidly attached to the main frame and provided withset'screws G G G G, which rest upon and abut against the upper surfacesof the axle-blocks. The axle is at its outer extremities provided withratchet-wheels K, rigidly attached thereto, and the supportingwheels 0are provided with pawls L, attachedthereto, the construction of theseparts being such that in the forward revolution of the supporting wheefsthe pawls engage with the ratchets and revolve the divided axle in thedirection of the moving machine. In the backward revolution of thesupportingwheels the pawls become disengaged from and slide over theratchets with the result that the axle remains stationary. One sectionof the di' vided axle, at its inner extremity, is provided with abevel-wheel, I, which gears into a pinion, J, mounted upon and attachedto the upper extremity of a vertical shaft, Q. provided at its lower'extremity with a hub, P, which carries the spokes of the circulartootlrframe or wheel,of which frame M and N, respectively, are the outerand inner rims, and O Othe toothshafts. The shaft Q is supported iii-andby a collar, Q, attached to the main frame A. The tooth -frame isprovided with supplemental radial tootlrshafts It, the extremities ofwhich are pivotally supported in the outer and inner rims, M and N,respectively. These shafts, at their inner extremities, are eachprovided with a vertical crank, T, which carries at its upper extremitya roller, T. The raketeeth S are intermediately of their length coiledabout and attached to the shafts R R, from which the working ends of theteeth depend.

To the under side of the main frame A. there is attached a semicircularand approximatelyhorizontal track or way, U, so constructed and arrangedthat the rollers T of the tooth-shaft crank may, when necessary, becaused to run under and in contact with its lower surface, with theresult that the teeth carried by that half of the circular tooth-framewhich is at a given time toward the forward part of the machine arecaused to be forced upon the ground by reason of the tooth cranks beingthrown downward in the direction of the free or sweeping ends of theteeth. cranks are, as shown in Fig. 2 at T, maintained in this depressedposition during the travel of the respective tooth-shaft rollers underand in contact with the track U, after which the coiled springs on thetooth-shafts assert themselves and cause the tooth-cranks to againassume vertical posit-ions, as shown in Fig. 2 at T.

The tooth-' In Fig. 6, U is a switch horizontally pivoted to the trackU, at the left side of the machine, the free end being held in anelevated position by a bolt, U, when the machine is in operation,whereby the tooth-crank rollers T are guided and caused to travel undersaid track.

\Vhen the machine is not in use, the switch U may be dropped to aposition below or on line with the track U, and there secured by thebolt U", whereby the tooth-crank rollers T are caused to travel upon theupper'surface of said switch U, with the result that all the teeth ofthe tooth-frame are supported above and out of contact with the ground.The thills \V are pivoted to the main frame A at X, the rear ends of thethills being pivotally attached to rods B, which slide verticallythrough blocks or sleeves 1V, above and below which are placedcushioning springs I).

To the block or sleeve A is pivotally attached the. lower forked arm, Z,of lever E, which is fulcrumed upon a block, 1 sprung from the platformI This lever is provided with an ordinary spring-latch and stop, E, bywhich the lever can be fixed at desired positions. The forked levers Z Zat the respective sides of the platform are connected to and by a shaft,Y. The thills are connected to the main frame at that side of the centerof the axle at which the ral ing-teelh, when in contact with the ground,exert a draft in opposition to the forward movement of the machine, asis shown in the drawings, whereby a side pressure and movement of thethills is, in the operation of the machine, prevented.

V are rollers attached to and depending from the main frame and adaptedto come into contact with the upper surface of the inner rim, N, of thetooth-wheel to steady its movement and prevent strain upon itssupportingshaft Q. A similar wheel is provided at the forward part ofthe machine, to assist in performing the same office.

Such being the construction of my machine, its mode of operation is asfollows: The circular tootlrcarryiug framehaving been adj usted at asuitable distance from the ground by the set-screws G- l G G, and themain frame having been tilted by the lever E so thatthe forward part ofthe tooth-carrying wheel has been adjusted sufficiently close to theground, and the rear part of said tooth-carrying wheel has been adjustedat a distance sufficiently remote from the ground, the machine is drivenforward, and the pawls of the road-wheels caused to engage with theratchet-wheels on the extremities of the divided axle and to revolve thesame, whereby, through the instrumentality of the bevel-wheel I and thepinion J, the tooth-carrying frame is revolved from the left side of themachine toward the right side, the teeth of the forward part of thetoothcarrying frame being in close contact with the ground, and theteeth of the rear part of said frame being out of contact with theground with the result that the hay or straw is swept into a windrowparallel with the direction of travel of the machine and at the rightside thereof.

It will be understood that this machine may be driven round the outeredge of a circle or proper adjustment of the switch U, causing thetooth-crank rollers to travel upon the upper side of the track U.
